Age, PRISM score, age specific risk of mortality, mortality, admission arterial pH, base excess, and lactate in children with normal (⩾ 7.32) and abnormal (< 7.32) pHi. Date are expressed as median (interquartile range) and analysed by the Mann-Whitney test except where indicated (*Fisher’s exact test)
